The design metal temperature for a tank
The design metal temperature for a tank
(OP)
As recommended in API 650, the minimum design metal temperature is the lowest one-day temp plus 8 dC. However, does it apply to an electrically heat traced or immersion heater heated tank? Seems too conservative if there is temperature gauge installed to monitor the temperature.
Any comments or experiences?
Thanks.

Go with the recommendation.
How the "lowest one-day temp" is determined may offer some latitude.

If it's a small tank, also consider using App. A, which will let you use some materials at colder temperatures than the standard code.
